“Ineffable” means “too great to be spoken in words,” so I’m wondering what you found sexualized about that.
replyA coworker made a sort of cartoon, pompous jerk says "Who dares disturb the ineffable blah blah blah"
replyCleaning lady: "Sorry I had no idea you wasn't effable, I'll come back later"
that is to say since effable as a slang term for some someone that one might like to have sex with exists, it is a reasonable pun to make with ineffable as being, well, not effable. However one should probably be able to realize the ineffable in question is not a pun on the slang term and figure things out. Somewhat embarrassing really.
on edit: added in disturb, must have missed it because very tired.
Another meaning the word "effable" acquired in the last couple decades is a spelled out form of "f-able", as in fuckable. OP must've been unaware of the word's prior existence.
replyYou'd have to deliberately misunderstand it, clearly if that's the first thing that pops up into your head when you read about someone putting together a memorial show for their mom that isn't the appropriate reading.
replyI think you perhaps misunderstood the meaning of some of the words used.
replyWhen in doubt, google. I had to google that word myself as a non-native speaker, nothing sexual there.
replyBowing down to one's mother ain't something to scorn on. As Jim Jefferies and many others said, show them some proper respect since there won't be another person in your life that will ever love you more, or even equally... at least under normal circumstances
